Golfsmith Cobalt Steel Pre-Reaming Drill Bit

The Golfsmith Cobalt Steel Pre-Reaming Drill Bit is perfect for re-boring hosels on club-heads made of notoriously difficult-to-drill metals such as 17-4PH, titanium, and marraiging steel. This HSS-CO alloyed and titanium-nitrated drill bit holds its rigidity and hardness at higher temperatures better than a HSS drill bit. Sized for enlarging hosel bores prior to reaming, this drill bit provide a good epoxy bond allowance between shaft and hosel.
